3.1.1 DHCP的安装

在FreeBSD上安装DHCP, 首先需要确定内核配置中有 `pseudo-device bpf'选项, 然后可以从ports下的 net/isc-dhcp3安装dhcp, 安装没什么好讲的, 直接安装就是了

3.1.2 DHCP的配置

我配置了一个简单的, 主要有下面的几个文件

/usr/local/etc/dhcpd.conf

option domain-name "unidevel.com";
option domain-name-servers 88.1.16.4;

default-lease-time 600;
max-lease-time 7200;

authoritative;

ddns-update-style none;

subnet 88.1.16.0 netmask 255.255.255.0 {
  range 88.1.16.150 88.1.16.200;
  option routers 88.1.16.4;
}
   

然后, 拷贝一个启动脚本

# cp /usr/local/etc/rc.d/isc-dhcpd.sh.sample /usr/local/etc/rc.d/isc-dhcpd.sh
# chmod a+x /usr/local/etc/rc.d/isc-dhcpd.sh
# /usr/local/etc/rc.d/isc-dhcpd.sh start
   

上面对88.1.16网段使用DHCP, 配置为主DHCP服务器, DHCP的网段为88.1.16.150 - 88.1.16.200, 缺省的路由器是88.1.16.4, 缺省的DNS为88.1.16.4
